Be it known that FRANK A. REYNOLDS, a citizen of the United States, residing at Circle, in the Territory of Alaska, have invented certain new and useful Improvements in 'lype-Writer Indicators, of which the following is a specification.

This invention relates to typewriter indicators, and more particularly to means for indicating the line spaces on a sheet of paper being written upon.

One of the main objects of the invention is to provide a device of the character stated of simple construction and operation which may be readily applied to typewriter oi standard construction. A further object is to provide an indicating disk rotatably mounted adjacent one end of the platen roll of a typewriter, the peripheral surface of this disk being graduated to indicate the line spaces through which the roll is turned. A further object is to provide simple and efficient means for securing this disk in rotary adjustment relative to the platen roll. Further objects will appear from the detailed description.

in the drawings:

Figure 1 is'a fragmentary front view of a platen roll with an indicating device constructed in accordance with. my invention. as applied.

I ig. 2 is a fragmentary central sectional view.

Fig. 3 is a section taken transversely of the axis of the platen roll adjacent the end thereof and looking toward the end of the roll.

Fig. i is a detail of the pawl for securing the indicating disk in rotary adjustment.

The platen roll 1 is of standard construction being provided with a spindle 2 on the end of which is secured the knurled handknob 3. A disk l is secured to the end face of the body 1 of roll 1 by means of screws 5 or equivalent securing means. This disk is provided with an integral neck 6 which extends outward and fits snugly about the spindle. Anindicating disk 7' is mounted on neck 2 for rotation thereon, being secured against axial movement by a collar 8 pro-.

vided at its inner end with. an outer annular flange 9 fitting snugly against the out/er face of disk 7. This collar is secured in position by a set screw 10 threaded through alined bores in the collar and neck 6 and Specification. a Letters Eatent.

an inwardly directed peripheral flange 11.

it. resilient arm 12 is secured at one end to the body oi disk 7 by means of a screw 13 threaded into the disk and fixedly secured to the arm. This arm is provided at itstree end with spaced depending ears i l which rotatably support an adjustment roller 15. This roller is adapted to engage the peripheral surface of disk 4 which is toothed or serrated for this purpose as in Fig. 3 of the drawings, the roller engaging between the teeth 16. its will he noted more particularly from this figure, the resilient arm 12 is so shaped that its end portion adjacent the screw 13 is arched outwardly to provide an abutment element 17 which engages the inner surface of flange 11. By this means, arm 12 acts to resiliently hold roller 15 in contact with the toothed peripheral surface of disk 4. This construction serves to normally secure the indicating disk-7 to the platen roll for movement therewith, while permitting independent rotary adjustment of the disk, the arm 12 and roller 15 acting to secure the disk in adjusted position relative to the roller.

The outer surface of flange 11 ofthe indieating disk is divided into a number of equal spaces, these spaces corresponding to the distance to which the platen roller 1 is turned to move the sheet of paper being written upon the distance of a double space, and each of these spaces on the flange 11 is numbered, the spaces being numbered in scriatim' order starting from numeral 1.

The flange 11 may also beprovided with any suitable number of positioning marks such as the arrows 18, these arrows being placed to correspond with the spaces marked 6 and 7. In using this device, the sheet of paper 19 tobe written upon is placed in the typewriter, the platen roller being turned so as to move this sheet upward the required distance." In Fig. lot the drawings, I have shown the' sheet 01" paper as being moved through six double spaces so as to bring the upper edge thereof in alinement with the positioning mark 18 adjacent number 6. If it is assumed that the sheet of paper 19 is of such length as to accommodate twenty-one lines of written matter with double spacing, and the platen roller 1 is of such diameter as ii iii lllii inner end turned inward to form a flange, a- In testimo y whereof, I have signed this I receptacle-shell located Within the said cap specification in the presence of two suband having its outer end turned inward to scribing Witnesses.
